2; Use additional material ог structure to reinforce, strengthen, prop, tie, and
support existing material or structure.
3. Use reversible processes wherever possible.
4. Use traditional replacement materials and techniques. New work shall be
distinguishable to the trained eye, on close inspection, from old work.
5. Record the work before the procedure with preconstruction photos and during the
work with periodic construction photos. Photographic documentation is specified
in Division 1 Section "Construction Progress Documentation.”
Prohibit smoking by personnel performing work on or near historic structures.
Obtain Architect's review and written approval in the form of a Constructive Change
Directive or Supplemental Instruction before making changes or additions to
construction or removing historic materials.
Notify Architect of visible changes in the integrity of material or components whether
due to environmental causes including biological attack, UV degradation, freezing, or
thawing; or due to structural defects including cracks, movement, or distortion.
1. Do not proceed with the work in question until directed by Architect.
Where Work requires existing features to be removed, cleaned, and reused, perform
these operations without damage to the material itself, to adjacent materials, or to the
substrate.
Identify new or replacement materials and features with inconspicuous, permanent
marks to distinguish them from original materials. Record the legend of identification
marks and the locations of these marks on Record Drawings.
When cleaning, match samples of existing materials that have been cleaned and
identified for acceptable cleaning levels. Avoid over cleaning to prevent damage to
existing materials during cleaning.

5. Dimension from face of concrete soffit to face of anchored veneer shall be a nominal 8".
6. Grouting:
a. All anchored ceramic veneer shall be set in a full bed of mortar and all voids back of the ceramic veneer shall
be filled solid with grout as specified under Grout Mix #1, and shall be well rodded to eliminate all air
pockets.
b. Where possible to do so, grout should be poured to a height of 6" only behind each continuous course of
anchored ceramic veneer and the grout allowed to set sufficiently to "freeze" the piece in place before
pouring the balance. Grout shall have sufficient plasticity to fill the joints from the rear.
c. All copings and cornices of handmade ceramic veneer shall have filler pieces (grout plugs) at joints.
d. Before being set in place, all handmade ceramic veneer copings, etc., shall be turned bottom side up and
filled solid with a lean wet grout as specified under Grout Mix #2, andshall later be set in place on the wall
and anchored in vertical joints as indicated on setting drawing.
e. Vertical joints shall be grouted solid through openings at joints, provided in ceramic veneer before grout
plugs are placed.
f. This pre-grouting procedure is also to be used in grilles, etc., as directed and whererequired to solidly fill all
voids.
C. Installing Adhesion Type Ceramic Veneer:
1. Setting:
a. Just prior to application of mortar coats, a limited area of the wall and the entire back of the piece of soaked
ceramic veneer about to be set shall be given a brush coat of neat portland cement and water.
b. Immediately thereafter spread on-half of th mortar coat on a limited area of the wall and the other half over
the back of the piece of ceramic veneer.
1. The mortar troweled on the back of the piece of ceramic veneer shall be screeded to a uniform
thickness as measured from the face of the ceramic veneer.
2. The other half of the mortar bed applied to the wall surface shall be screeded to a true and plumb
level.
3. The total thickness of the mortar coat shall average 3/4", but sufficient mortar shall be used to create
a slight excess which will be forced out at the joints at the edge of the piece when it is tapped into
place.
c. When the piece is set against the wall it shall be driven home by repeated tapping with a rubber mallet to
GSA
f. Any piece of ceramic veneer tipped away from the wall for readjustment or improperly set for any reason
shall immediately be removed, cleaned of all mortar, including the wall surface, and reset in accordance with
the above procedure.
2. Soffits: Each piece of ceramic veneer, in addition to the usual centers and wooden wedges, shall be supported by
suitable bent vertical wooden shores exerting a constant upward pressure until the mortar coat is set for several
days.
D. Tooling and pointing:
1. If pointing is not specified, all mortar joints shall be tooled as the setting progresses to form a concave joint.
2. When pointing is specified, all mortar joints shall be raked to a depth of 1/2".
3. Before pointing, joints shall be saturated with clean water, after which they shall be filled solidly with pointing
mortar and tooled.
4. All surplus mortar and stains shall be removed as the setting progresses and the surface shall be left clean.
3.03 ADJUSTING/CLEANING

new plaster. Re-attach loose lath or install new lath as required.
6. Spray existing plaster to be pointed or patched with water, or use bonding agent, to ensure adhesion of new plaster. Install
keying systems for larger pieces as necessary. Comply with referenced standards.
7. All existing plaster to be painted shall be stripped down to a bare finish plaster surface with a non-water based solvent of
paint stripper which cannot be water flushed clean.
8. Measure and layout ornamental plaster accurately to maintain pattern and alignment of the work.
3.03 ERECTION, INSTALLATION, APPLICATION
NOTE: Conform to the requirements of the latest edition of "Gypsum Construction Handbook" published by USG Corporation
concerning application of ornamental plaster.
A. Make a template from sheets of metal (brass) cut full-scale in shapes to match existing; use to screed or form gypsum plaster to
desired shapes and contours.
1. Coat metal sheet with layout dye - a blue dye that makes the scribed pattern easier to follow.
2. When the dye is dry, scribe, cut and carefully file the template to remove any roughness or other imperfections that might
be transferred to the finished work.
3. Use a sled to guide the template as it is pushed through the plastic mass. Basic parts of the sled include a "slipper-board"
and the board to which the template is nailed.
a. For bench work the sled is guided by the table edge. Bench-run molds are installed on the job with mechanical
fasteners or adhesively attached with gypsum plaster.
b. For run-in-place work, a guide strip is attached to the wall or ceiling and forms one edge of the pattern; after work is
completed the guide strip is removed.
4. For circular shapes:
a. Follow procedures described in Section 3.03 A.1.- A.3. above, except scribe the center line of the circular shape on
the template.
b. Center a pivot plate to this line and attach to the template board.
C. Mix Plaster: Use special plaster designed and manufactured for ornamental plaster work.
NOTE: Міх the plaster a little below normal consistency for the first mix, then allow the mix to "cream" a bit before placing it on the
bench in front of the template. For run-in-place work a slightly stiffer consistency is desirable.
1. For Hand Mixing:
a. Weigh the plaster, and measure or weigh the water.
b. Sift plaster into water evenly. Do not drop handsful of plaster into the water at one time.
c. Allow to soak 2 minutes undisturbed, then mix thoroughly. Stir from bottom, forcing material to top. Take care to
avoid beating air into mix. Proper mixing forces air out of mix.
d. Continue mixing until a smooth, even mass is produced.
2. For Mechanical Mixing: Mechanically mix cementitious and aggregate materials for plasters to comply with applicable
referenced application standards and with recommendations of plasters manufacturer.
a. Weigh plaster and measure water accurately.
b. Sift or strew plaster slowly and evenly.
c. Allow it to soak 2 to 5 minutes, and mix for 2 to 5 minutes.
NOTE: For batches of 10 to 50 lbs., use a 3" diameter, 3-blade, 25 degree pitch propeller with 1/4 or 1/3 hp. 1,760 rpm direct-drive
motor. For batches of 50 to 200 Ib., use a 4" diameter, 3-blade, 25 degree pitch propeller with 1/2 hp. 1,760 rpm direct-drive motor.
D. Replicate the Ornamental Trim:
1. For Run Work or Straight Mold:
NOTE: This method is used to produce staff work or pattern stock having parallel edges or to form a straight molding.
a. For bench work, some plaster should be allowed to lap over the end of the bench to act as an anchor and prevent
GSA
2. 2. For Circular Shapes (Turning): Like run work, turning can be done in the shop or run-in-place.
a. For bench work, place a center post in a hole in the bench.
b. For run-in-place work, position the center post accurately at the center of the circular shape to be formed and
securely attach or brace to the structural supports.
NOTE: THE CENTER POST SHOULD HAVE A RUNNING THREAD, WITH A DOUBLE NUT FOR HEIGHT ADJUSTMENT. THE
PIVOT POINT MUST BE ABSOLUTELY RIGID AND SET HIGHER THAN THE TOP OF THE PATTERN TO BE MADE, SO THAT
THE TEMPLATE WILL SCREED CLEARLY AS IT ROTATES AROUND THE PIVOT POINT.
3. Duplicate plaster molds by taking impressions from existing plaster molds; create new rubber molds from these
impressions and cast plaster into these molds.
4. Remove plaster molds after plaster has cured, following plaster manufacturer's instructions.
5. Strip and clean existing decoration to produce a clean, sharp mold.
3.04 ADJUSTING/CLEANING
A. When replication and plasterwork is completed, remove unused materials, containers and equipment. Clean floors and adjacent
surfaces of all plaster debris, including plaster droppings daily.
B. Provide final protection and maintain conditions, in a manner suitable to the RHPO, which ensure ornamental plaster being
without damage or deterioration at time of substantial completion.

PART 3---EXECUTION
3.01 PREPARATION
A. Surface Preparation:
1. Remove ornamental plaster that is damaged or loose and requires replacement, or that has to be reset.
2. Reinforce and secure loose ornamental plaster that is to remain, using appropriate concealed methods.
3. Clean plaster surfaces to be restored, to remove loose and deleterious materials that may affect adhesion or application of
new plaster. Reattach loose lath or install new lath as required.
4. Spray existing plaster to be pointed or patched with water, or use bonding agent, to ensure adhesion of new plaster. Install
keying systems for larger pieces as necessary. Comply with referenced standards.
5. All existing plaster to be repaired shall be stripped down to a bare finish plaster surface with a non-water based solvent or
paint stripper which is not water flushed clean.
3.02 ERECTION/INSTALLATION/APPLICATION
NOTE: IT IS NOT ALWAYS NECESSARY TO DETACH THE PLASTER ORNAMENT IN ORDER TO DUPLICATE IT. HOWEVER, IF THE PLASTER
ORNAMENT CAN NOT BE REMOVED FROM THE WALL OR CEILING TO MAKE THE MOLD, CURING MAY TAKE SEVERAL DAYS BETWEEN
LATEX COATS AND SEVERAL WEEKS FOR THE FINAL CURING.
A. Making the Mold:
1. Detach from the ceiling or wall plaster casting to be duplicated.
2. Patch the fragment or fill in any damaged portions of the pattern using spackle or other patching compound.
3. Carefully clean the fragment for mold making.
4. Brush the master piece with the rubber latex.
5. Cure the latex at a temperature of about 1100F.; Use an infrared heating lamp, an electric hair dryer, or a warm oven to
provide the source of heat; Cure for about 1 hour using heat.
6. When the rubber has cured, apply a second latex coating (the number of coats required is dictated by the size of the original
and the depth of the relief); Cure as above.
B. Building the Mother:
1. The purpose of the mother is to support the mold when it is filled with wet plaster.
GSA
the mold.
4. Separate the mother from the rubber mold as soon as the plaster has set (in less than an hour).
5. Wash the interior of the mold with soap and water and remove any residual byproducts left from the curing process.
C. Mixing the Plaster:
1. Add 7 parts by volume of plaster to 4 parts water; Use cold water to retard the set-up time.
2. Sprinkle plaster powder in slowly; Stir as little as possible.
D. Casting the Plaster:
1. Before pouring plaster into mold, fill the mold with water and then pour water out (this will moisten the walls and ensure
penetration of the plaster into all crevices).
2. Add plaster and cheesecloth or burlap strips for strength; Jog the plaster-filled mold gently to nudge plaster into all the
indentations.
3. Level the plaster; Plaster should be hard enough to remove from the mold in 30 minutes; Allow 24 hours to air dry before
installing.
E. Install the plaster casting using a thin coat of plaster of paris as an adhesive; Hold the piece in place for a few minutes until the
plaster sets; A mastic adhesive or epoxy or gypsum board joint cement are other good adhesives for light pieces.
